Matthew has beefed up for his role as a triathlete in ‘Me Before You’, which also involved ditching carbs, sugar and alcohol.

Good to see Matthew Lewis kept his cardi on. We wouldn't want him getting cold.

Speaking about his role playing Patrick in the movie, Matthew tells Attitude: “I spoke to the director and I said it’d be nice to get into the mindset of someone like Patrick, because he’s not drinking alcohol, he’s just eating salads all the time.

“I was very interested to know where you go to in your mind to have that level of commitment. So I sort of gave up alcohol – I say sort of, I have given up alcohol.”

And for someone who used to enjoy having a tipple, it hasn’t been the easiest of rides by the sounds of it

“It’s tough,' he adds. “I do the pub quiz every week, and I'm sitting there every Wednesday with a Diet Coke... I’m off sugar and I can’t really eat carbs.

“I really wanted to see if I could stick to such a strict regime, and to really understand what it’s like to have a goal like that and really 110% go for it.

“I mean I’ve always been a bit of a sports enthusiast anyway, I love the gym and all that stuff, but I can’t wait for a pint of lager, I tell you that! The pizza and beer will definitely be making a comeback over the summer.”
